CUSTOM METAL GASKETS

Advanced Gasket & Supply offers spiral wound gaskets in a variety of styles to suite your particular flange facing.
Spiral-wound gaskets are made of a preformed metallic strip and a soft filler material wound together under pressure, with an outer guide ring.
They are constructed with a metallic guide ring, metallic winding, and a filler element. The winding is manufactured from metal in a complicated form of a spiral, in assembly with a filler material. The filler materials fill the irregularities of the flanges. It's external guide ring has the function of centering the gasket in the flanges and gives the sealing elements additional resistance to the flow pressure and excessive bolt torque.
For applications with high temperature variations (thermal cycling), andor pressure variations, andor flange rotation problems etc., gaskets with adequate residual stress (stress retention), and flexibility are needed. Our spiral-wound gaskets have been designed to meet these demanding requirements.
